Elements (I also changed a few old ones, like THDR goes really quickly to look like thunder, PLUT is stupidly powerful, etc, THDR is in Explosives menu, etc)

--electronics--

IMTL - Indestructible, unmeltable metal.
IBTR - Indestructible battery

--explosives--

SPRT - Sprites. Upward thunder.
FUEL - Weird liquid explosive.
HEXP - Basically gunpowder, but a different colour. Requested by one of my friends at school to look nice as a fuel for his rocket.
DYNA - Dynamite. C4 with a plasma explosion.
BRNZ - Barenzitite (I just made it up) is an explosive gas.
JKSN - Jacksonium turns all particles to fire on contact.
BMAG - Burning Magnesium.

--gases--

SYGG - Super Yeast Grow Gas. At 37 degrees, so it helps yeast to grow.
GMTL - Gas metal. Basically floaty lava.
CDOX - Puts out fires (I think) and causes photosynthesis in PLNT.
QUIN - Quininite burns Barenzitite. It is flammable.
H2 - Hydrogen add Oxygen equals water.

--Liquids--

MCHC - Melted chocolate.
LGLD - Liquid gold
LSLV - Liquid silver (Next version, these and their solid counterparts will be conductive)
LCOP - Liquid copper
GLOP - Gloop. Heals STKM.

--Liquids II--

SACD - Super Acid.
LWTR - Add CDOX to make LIME.

--Powders--

LIME - Limestone. Heat to make QKLM.
QKLM - Quicklime.
PINS - Pressure insulator. Helps to keep pressure at zero.

--Solids--

CHOC - Stickman will eat if his head touches it.
GOLD - Melts at high temperatures.
SLVR - Melts at high temperatures. (These three will conduct electricity in next version.)
COPR - Melts at high temperatues.
MAGN - Try burning Magnesium.
RUB - Goo, but it doesn't disappear.

--Radioactives--

FRCM - Don't let Francium touch Water.
LASR - Laser is very hot photons.
ROBN - Robinium turns to neutrons at high temperatures.
NEPT - Neptunium decomposes into NEUT after a short time.

--Living--

(WOOD, PLNT, YEST, DYST are here)

SEED - Creates a plant when watered.
LEAF - Generic, burnable stuff.
GERM - Eats organic matter.
VIRS - All non-Special particles turn to VIRS when they touch it. Flammable.

--Special--

CSTF - Cold stuff. Keeps the temperature low.
HETR - Heater, that tutorial element from the wiki. Heats stuff up.
MOVS - I tried to make a moving solid. I failed. I removed the 'move' code and left this in. Use this as an alternative to DMND.
GRAV - BHOL that doesn't suck particles up.

Yeah, that's about it. I'm using the source with AMTR, PCLN, HSWC, FIRW, CFLM, FSEP, BCOL btw.

It's in interface.h. Erm...

Under the Walls bit at the top, you should have something like this:

#define SC_WALL 0
#define SC_ELEC 1
#define SC_EXPLOSIVE 2
#define SC_GAS 3
#define SC_LIQUID 4
#define SC_LIQUIDII 5
#define SC_POWDERS 6
#define SC_SOLIDS 7
#define SC_NUCLEAR 8
#define SC_LIVING 9
#define SC_SPECIAL 10
#define SC_TOTAL 11

static menu_section msections[] =
{
{"\xC1", "Walls", 0},
{"\xC2", "Electronics", 0},
{"\xC3", "Explosives", 0},
{"\xC5", "Gasses", 0},
{"\xC4", "Liquids", 0},
{"\xC4", "Liquids II", 0},
{"\xD0", "Powders", 0},
{"\xD1", "Solids", 0},
{"\xC6", "Radioactive", 0},
{"\xA3", "Living Things", 0},
{"\xCC", "Specials", 0},
};

At the top, where it says #define SC_LIVING 9, it means that the section should be called SC_LIVING, and it should be the ninth on the menu, and in the table bits of the code.

{"\xA3", "Living Things", 0}, - "\xA3" is the menu icon, and "Living Things" is the little white text over the menu when you hover over an item on it. Not sure what the 0's about, though.

Yeah, they're all like \xA3, \xDD etc.

I think there's about 15 or 20 of them.
